Barcelona, who failed to score in a Champions League group game for the first time since December 2012, face Sevilla at Camp Nou on Saturday before a two-week international break.

They will hope to do better in front of goal at the weekend after failing to capitalise on their dominance against Olympiacos, who clung on in the second half to pick up their first point of the campaign.

"We played well but we lacked a finish and that's the most important thing," midfielder Sergio Busquets told the media.

"We tried everything, we created good chances, we hit the woodwork, but sometimes the ball won't go in.

"We just continue now. We are in a terrific position and what's more out of every 100 games we play like that one we'd win 95 times."
